Portocath insertion technique: retrospective study & step-by-step surgical description without tunneling in a high-complexity service.

Objective: to demonstrate that the use of the portocath implantation technique without tunneling the catheter is not associated with a higher rate of complications in the short or long term. In addition, we aim to improve the implantation technique of the portocath device, with the presentation of a step-by-step guide for surgeons in training.
